Centaurea scabiosa ssp. fritschii (Hayek) Hayek, syn: Centaurea fritschii Hayek, Centaurea grinensis Reuter ssp. fritschii (Hayek) Dostal, Centaurea scabiosa ssp. grinensis (?) (Ref.1)Fritschi's Greater Knapweed, DE: Zartblat-Scabiosen-FlockenblumeSlo.: Fritschev glavinecDat.: June 12. 2014Lat.: 46.33366 Long.: 13.59288Code: Bot_803/2014_IMG5818Habitat: partly overgrown, sandy and stony mountain slope, roadside; southeast aspect; calcareous, skeletal ground; locally open space, otherwise in mixed wood, Ostrya Carpinifolia; Fagus sylvatica, Picea abies, Fraxinus ornus, Corylus avellana dominant; partly sunny, relatively warm place; exposed to direct rain; elevation 420 m (1.400 feet); average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, alpine phytogeographical region. Substratum: sandy soil.Place: Bovec basin, at 'Girhlca' place, above the main road Bovec-Vri, East Julian Alps, Posoje, Slovenia EC Comment: Genus Knapweed (Centaurea) is taxonomically a difficult one. Fisher et all (2005) adds to all species names described in the Ref.1. signs (small black squares) which mean: " ... taxonomically critical, the key states more problems than solutions...". Plants are very variable, particularly their leaves. Centaurea scabiosa ssp. fritschii was at the beginning described on species level (Basio: Centaurea fritschii Hayek) and later shifted to subspecies level. It has only been botanically described at the beginning of the last century. Ref. 2 states that its distribution in Slovenia is not yet sufficiently studied. It should be endemic since it is known only from northeast most Italy, south Austria and Slovenia (Ref.3). But it is not included into the trilogy W. Langer / H. Sauerbier et all (1997-2005), Endemishe Pflanzen der Alpen (Ref.: 4, 5, 6). Anyway, an interesting plant, which is not at all rare in the Upper Soa valley. Eventually it builds yellowish-pink blooming hybrids with another very interesting, yellow blooming, knapweed Centaurea dichroantha Kern., which is a famous narrow endemic of Soa valley and a few valleys to the west in Italy.Ref.:(1) M.A. Fischer, W.

Sallent de Gllego. Los Pirineos: Aragn (Espaa) Comentarios sobre el nombre: Se incluyen en una sola ficha los comentarios de las subsp. montana y semidecurrens, dados los sutiles caracteres por los que se distinguiran, y las dificultades para separar sus reas de distribucin. - la de la foto es casi con toda seguridad la subsp montana-.Familia: ASTERACEAE (COMPOSITAE)Distribucin: Endemismo de las montaas de Europa central y meridional, desde los Alpes hasta el Pirineo y Sistema Ibrico. En Espaa se distribuye sobre todo por las montaas del cuadrante NE. En Aragn es rara en zonas del Alto Pirineo y Prepirineo, y parece ser rarsima en las sierras orientales (Gdar y Beceite) del Sistema Ibrico turolense. Para el Sistema Ibrico todas las localidades corresponderan a la subsp. semidecurrens, segn Lpez Udas (2000). Hbitat: Orlas herbosas de diversos bosques, pastos mesfilos de collados, pastos supraforestales, en general sobre terrenos calcreos, por zonas de montaa media y alta, pirenaica e ibrica, sin bajar a los ridos parajes de la Depresin del Ebro.Preferencia edfica: Basfila Calccola Rango altitudinal: ( 750 ) 1100- 2000 ( 2350 ) m Floracin: Junio - AgostoForma Biolgica: Hemicriptfito escaposo Extractado del Atlas de la Flora de Aragn (Herbario de Jaca)
